Primary Reaction Control System (Primary RCS)
A clustered array of small thruster nozzles, piping and control valves mounted around the shuttle’s hull, built from heat‑resistant alloys and blackened by exhaust. Compact vernier jets and attitude nozzles sit in groups; technicians refer to it as the shuttle’s fine‑motion toolkit. In Toby’s office the system is invoked verbally as the immediate alternate control path after OMS engine failures, its capacity treated like a fragile, last‑chance mechanism the team must rely on under extreme time pressure.

Purpose
Provide short impulse thrusts for attitude control and small translational maneuvers, enabling spacecraft orientation and backup maneuvering when primary main engines (OMS) are compromised.
Significance
Functions as the operational fallback that can avert catastrophe: its proposed activation pivots the scene from personal confession to urgent remediation. The Primary RCS becomes a technical lifeline and a narrative fulcrum, shifting responsibility, strategy, and emotional stakes for Toby, Sam, Cathy, and command.
